How to subtract a year from leap year

I'm looking for a solution for the following:

$date = new DateTime('02/29/2020');
$date->sub(new DataInterval('P1Y'));
$date->format('m/d/Y');

This Returns: 03/01/2019

Is there a way to return 02/28/2019? Thanks

Solution

  • date('L') returns true if a leap year, so:

    <?php

$date = new DateTime('02/29/2020');
$date->format('L') && $date->format('m-d') == '02-29' ? 'P366D' : 'P1Y';
$date->sub(new DateInterval($interval));
echo $date->format('m/d/Y');
